save bitmap menu

--------------------------------
This menu is for creating new bitmap images that contain selected objects from the image you analyzed. The procedure is:

  1. Enter the name you want for the new bitmap in the Bitmap file menu field.
  2. Set the Exteriors? and Interiors? toggles to control how the objects are created in the new bitmap image. See below for more about this.
  3. Set the Run-length encode? toggle to control whether the system encodes the bitmap image. Run-length encoded bitmap images are usually smaller, and they can be analyzed more quickly. Very complex bitmaps, however, can end up being much larger if they are encoded.
  4. Click on the CREATE BITMAP FILE menu field.

As with vector and statistics file creation, the system uses the following scheme to determine which objects will make it into the bitmap image:

You can control the form of the objects that make it into the bitmap image by adjusting the Exteriors? and Interiors? toggles. There are three meaningful setting for these toggles:

  1. Exteriors? set to Yes, Interiors? set to Yes: the objects are stored just as they appear in the original bitmap image.
  2. Exteriors? set to Yes, Interiors? set to No: the objects are stored with all of their holes filled in. This can result in smaller image files if you are not interested in the holes.
  3. Exteriors? set to No, Interiors? set to Yes: only the holes are stored in the bitmap image. This is useful if you want to analyze the holes in objects rather than the objects themselves.
